The most common reasons your tablet loses WiFi

A tablet that won't connect to WiFi usually has one of four problems: the WiFi is turned off on the tablet itself, you are out of range of the router, the router needs to be restarted, or the tablet has forgotten the network password. Start by checking whether WiFi is actually enabled — swipe down from the top of the screen to see your quick settings, and look for a WiFi icon. If it is greyed out or shows an X, tap it to turn WiFi back on.

If WiFi is on but your network does not appear in the list, move closer to the router. Most home routers broadcast a signal that reaches 150 feet in open space, but walls, metal, and other electronics reduce that range. Walk toward the router while watching the available networks list — if your network suddenly appears, distance was the problem.

If your network appears but the tablet will not connect, or connects and then drops, the router itself may need restarting. Unplug the router's power cable, wait 30 seconds, and plug it back in. This clears the router's memory and often fixes connection problems that affect multiple devices.

Key Takeaways

  • Check that WiFi is turned on in your tablet's quick settings — it is often disabled by accident or after a software update.
  • Move closer to the router; most home routers only reach reliably 100 to 150 feet, and walls block the signal significantly.
  • Restart the router by unplugging it for 30 seconds, which fixes most connection drops and slow speeds.
  • Forget the network on your tablet and reconnect by entering the password again, which clears corrupted connection data.
  • Check whether other devices can connect to the same WiFi; if they cannot, the problem is the router or internet service, not the tablet.

How to forget and reconnect to your WiFi network

If the tablet connects but drops the connection repeatedly, or connects very slowly, the tablet's memory of the network may be corrupted. Go to Settings, then WiFi, and find your network name in the list. Press and hold it (or tap the gear icon next to it, depending on your tablet's operating system) until a menu appears with the option to forget the network.

After you forget the network, it will disappear from the list. Wait a few seconds, then look for it again — it should reappear. Tap it, enter the WiFi password (the one printed on the back of your router, or the one you set up when you installed it), and tap Connect. The tablet will now store fresh connection information instead of using the old corrupted data.

When the problem is your router, not your tablet

If your tablet still will not connect after restarting the router and forgetting the network, check whether other devices can connect to the same WiFi. Use a phone, laptop, or another tablet — anything that has WiFi. If those devices connect without trouble, the problem is specific to your tablet and you may need to reset it or contact the manufacturer.

If other devices also cannot connect, or connect and drop repeatedly, the problem is your router or your internet service. Restart the router again and wait five minutes for it to fully boot up. If the problem persists, contact your internet service provider — they can check whether your connection is working on their end and send a technician if needed.

You can also try moving the router to a more central location in your home, away from metal objects, microwaves, and cordless phones, which all interfere with WiFi signals. Routers work best when placed on a shelf or mounted on a wall rather than hidden in a cabinet or closet.

Checking your tablet's WiFi hardware

If your tablet has never connected to WiFi, or stopped connecting after a drop or physical damage, the WiFi hardware itself may be broken. Restart the tablet completely — not just putting it to sleep, but powering it all the way off and back on. Hold the power button until you see a shutdown menu, select Power Off, wait 10 seconds, then press the power button again to turn it back on.

After the restart, go back to Settings and WiFi to see if your network now appears. If it does not, and other devices work fine on the same router, the WiFi receiver in your tablet may need repair. Contact the tablet's manufacturer or visit an authorized repair center — this is usually not something you can fix yourself.

WiFi password and security issues

If you recently changed your WiFi password, your tablet is still trying to use the old one. Go to Settings, WiFi, find your network, and forget it. Then reconnect and enter the new password. Make sure you type the password exactly as it is — WiFi passwords are case-sensitive, meaning capital letters and lowercase letters are different.

If you do not know your current WiFi password, you can find it on the back of your router, or log into your router's settings page through a computer or phone. Open a web browser and type the router's IP address (usually 192.168.1.1 or 192.168.0.1) into the address bar. You will need the router's admin username and password, which are also usually printed on the back of the router.

When to do a full reset of your tablet

If you have restarted the tablet, forgotten and reconnected to the network, confirmed that other devices work on the same WiFi, and the tablet still will not connect, a full reset may help. This erases everything on the tablet and returns it to factory settings, so back up any photos, documents, or other files first.

Go to Settings, find System or About, and look for an option called Reset, Factory Reset, or Erase All Data. The exact name and location depend on whether you have an iPad, an Android tablet, or another brand. After the reset completes, set up the tablet again and try connecting to WiFi. If it still will not connect, the WiFi hardware is likely damaged and needs professional repair.

Frequently Asked Questions

Why does my tablet connect to WiFi but then disconnect after a few minutes?

This usually means the router is too far away, the signal is weak, or the router needs restarting. Try moving closer to the router and restarting it by unplugging it for 30 seconds. If the problem continues, forget the network on your tablet and reconnect. If only your tablet has this problem and other devices work fine, the tablet's WiFi receiver may be failing.

Can I connect my tablet to WiFi without knowing the password?

No — you need the correct password to connect to a secured network. If you do not know it, check the back of your router where it is usually printed. If you have changed the password and forgotten it, you can reset the router to factory settings by holding the reset button for 10 seconds, which will restore the original password printed on the router.

Does my tablet need to be updated to connect to WiFi?

Sometimes. If your tablet is very old and your router is new, they may not support the same WiFi standard. Most modern routers broadcast on both 2.4 GHz and 5 GHz frequencies — try connecting to the 2.4 GHz network instead, which older tablets support more reliably. Check your router's settings or the sticker on the back to see which networks are available.

What if my tablet shows the WiFi network but says "cannot connect"?

This usually means you entered the password wrong, or the router is blocking your tablet for some reason. Forget the network, wait 10 seconds, and reconnect while carefully re-entering the password. If that does not work, restart the router. If the problem persists only with your tablet, try a full factory reset as a last step before contacting the manufacturer.
